PHILIP M. MALONEY, OF PHILADELPHIA, PENNSYLVANIA.

BOAT STOPPING AND HOLDING D EVICE.

SPECIFICATION forming part of Letters Patent No. 761,746, dated June 3, 1902. Application filed May 28, 1901. Serial No. 62,247. (No model.)

To all whom it may concern.-

Be it known that I, PHILIP M. MALONEY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Boat Stopping and Holding Device, of which the following is a specification.

My invention relates to a platform-frame or set of rollers wholly or partly submerged by water, hinged at one end and'free to be raised at the other, thus forming an incline on which approaching boats slide by their momentum and are thus held fast until released by the lowering ofthe movable end of platform or frame. I attain these objects by the mechanism illustrated in the accompanying drawing, which is adetailed view in perspective.

The platform Ais hinged at B and C and raised at the other end to desired height to suit depth of water, momentum, &c., by arms D or cams fixed to shaft E and operated by lever F or otherwise. If the method of operating is by lever F, the desired adjusting is obtained by the teeth in plate G. H H H are bearings for shaft E. Arms D here illustrated have rollers to reduce friction. When lever F is released from guide G and thrown to position shown by dotted lines, platform" A drops to level of hinge end and allows boat to pass over. Platform A may also be raised by levers I, hinged to frame or platform A at each B C and J K.

- What I claim as my invention, and desire to secure by Letters Patent, is-

1. An inclined frame for stopping and holding boats pivoted at its lower end beneath the water-level and provided with means for raising and lowering-the upper end.

2. An inclined frame for stopping and holding boats pivoted at its lower end beneath the water-level and provided with pivoted arms for raising and lowering the upper end.

3. An inclined frame for stopping and holding boats pivoted at its lower end beneath the water-level and provided with arms for rais- PHILIP M. MALONEY.
